To all whom it nut 1 /066776: shaft as may be preferred, from which abelt Be it known that I, GEORGE Q. ADAMS, a F extends to a pulley G,located on a countercitiZen of the United States, and a resident shaftII. There also extends upwardly a belt of Quincy, in thecounty of Adamsand State I, which passes over a flanged pulley .I on a of Illinois,have invented a certain new and counter-shaft- K at the upper part ofthe ma- 5; useful Roller Feed for Power Fence -Ma chine. On this shaftare located thefollowing chines, of which the following is aspeciticawheels: first, a grooved pulley Ii; next, the

Thus the rotation of the feedrollers M and N isintermittent, depending upon whether the roller L on the shaft K is uponthe larger diameter of the wheel R or not. It willthus be seen that thefeed-rollers operate to feed the pickets into the machine at the propertime only, and that there is no possibility of the pickets being takeninto the machine at an improper time. Thus accident or fracture to themachine from this cause is obviated.

, It will be at once perceived by those who are familiar with this artthat various modifications of the details of construction mav be madeand stillthe essential features of my invention be present.

l. The combination, in a fence-making machine, of an upper and lowerfeed-roller constructed and arranged to have intermittent separationfrom each other and driving mechanism forthe rollers, constructed andarranged so that when the rollers are separated they will be at rest,substantially as set'forth.

2. The combination, in a fence-making machine, of two sets offeed-rollers, one set constructed and arranged to have intermittentseparation from the other, and driving mechanism for both sets ofrollers, constructed and arranged so that they shall be at rest when thefirst set of rollers is separated from the other, substantially as setforth.

3. In a fence-making machine, a Wheel having two diameters, a shaftsupporting a feedroller, the end of the shaft to which the feedroller isattached being capable of limited downward movement, a roller upon theshaft, which engages with the larger diameter of the wheel having twodiameters, a flanged pulley on the shaft, and a belt going over somemoving part'of the machinery placed below the said shaft, substantiallyas set forth.
